To all whom it may concern:

Be it known that we, EDWARD N. TRUMP, a I

' resident of Syracuse, Ononda a county, State same s table spaced below the lower extension there- "of. Into the space between the envelop and the platform of each receptacle projects an adjustable deflector ada ted to encounter the material rotated there y. proportioning and adjustin of t ese respective deflectors and also by t e proper-regulation of the speed of rotation of the receptacles the required feed from-eachreceptacle, respectively, to any desired point may be secured.

Our invention also comprises means for deflectin the several materials so that the all fall together one upon the other, and thereby become thoroughly mixed and commingled in the falling.

. Our invention also comprises improved -means for the independent and accurate adof the deflectors, each provided justment I with a'micrometer scale and polnter to 1nd1- cate the" amount of adjustment.

Our invention also comprises improved means for supplying materials to the several receptacles.

Our invention also comprises improved I means for mclosing the several rotating movable seal.

masses with an approximately dustproof Ourimproved means-is especially adapted for measuring and mixing cement, sand, and stone for concrete, for measuring and mixing various'chemicals, for measuring and mixjn dry colors, for feeding cementmaterials am l coal to rotary kilns in such regular manner as to prevent the formation of rings in the kilns,

'for measur and- IIllXlIlg lune, sand, and

B the proper secured together the top of stationary post 8,

plasters, for bending cofiees,and for measuring and mixing flours, sugar, &c., in bakery and confectionery establishments. In fact, our improved means is applicable for use in various industries in whic materials are handled in bulk.

We accomplish our object by. the mechanism illustrated in theaccompanying draw in which in s, igure 1 isja plan view of our device in part section on line 3 3 of Fig. 2. Fig. 2 is a vertical section on line 2 2 of Fig. 1, with the exception of the pulley and shaft shown in elevation. Fig. 3 is a detail in perspective of a deflector and adjustable means therefor. Fig. 4 is a sectional detail, on an enlarged scale, of the step-bearing. Fig. 5'is aneleva-,

tion, on an enlarged scale, of a portion of the casing with the deflector-adjusting mechanism.

Similar numerals refer to similar parts throughout the several views.

In the device illustrated in the drawings We have rovided three receptacles-one composed o the cylinder 1 and platform-2., the second com 4, and the t rd composed of cylinder 5 and platform 6. Eachcylinder is spaced'a short distance above its respective platform, and each platform has a horizontal extension beosed of cylinder 3 and platform yondthe periphery of its respective cylinder suflicient to en port any spread of the *material beneath t e lower edge of the cylinder 1 due to natural slo e. Thesecylinders are all y radial arms, such as. 42 and 43, (see Fig. 2,) and supported by 'acentral sleeve 7 which is connectedwith the'inner cylinder 1 by radial arms, such as 44. The central sleeve 7 has a step-bearing at 47. on

rovided, prefsteel washers erably, with hard bronze an (Not shown.)

and roper oiling means.

Said s eeve 7 also has ajournal-bearingat' 48 about the lower extension of post 8. The lower table or platform 2 is provided on its under side with a beveled. gear 9, driven by 10 on counter-shaft 11, the coun-, oer-shaft 11 being'driven by the pulley 12- the pinion from any suitable source of power, such as the rheostat-controlle'd motor 41. It will thus be seen that all three receptacles have a simultaneous rotation about a common axis;

The deflectors 13, 14, and 15 are ivotally mounted on the vertical post 16 an extend over the tables 2, 4, and 6, respectively, and

beneath the lower extensions of the cylinders 1, 3, and 5, so as to encounter and deflect from each receptacle the under portion of the material rotated thereby. The platforms or tables are all of uniform diameters and the deflectors are so positioned as to deflect the material from the rotating tables at points approximately in vertical alinement with the aperture or conductor 17 delivering into any suitable receptacle. (Not shown.) By this means the material'deflected from cylinder 5 will fall into and commingle wit-h the material deflected from cylinder 3, while said commingled materials will in turn fall into and be commingled with the material deflected from cylinder 1, so that the three materials will fall through aperture 17 in a thoroughly mixed and commmgled state. Any desired order of mixing of said materials may be readily secured by this mechanismthat is to say, since the material from 5 is first mixed with the material from 3 and that mixture is then mixed with the material from 1, it is obvious that the desired order of mixing the different materials is secured by the proper distribution of the respective materials to the receptacles.

The several receptacles are each connected through openings 18, 19, and 20, respectively, by chutes such as 21 and 45 (shown in Fig. 2) with storage-bins or other suitable sources of supply. By this means the material is delivto the receptacles by gravity. By roviding the respective openings with con uctors such as 22, (shown in Fig. 2,) extending downwardly into the cylinders a short distance, it will be obvious that the material will be fed therethrough into the cylinders until the same are filled to the lower margins of said conductors 22, as shown in Fig. 2, whereupon the supply of material to each cylinder will be automatically stopped. In other Words, thesup l of material to the various receptacles will fie automatically controlled so that said receptacles will always be maintained filled'to the samelevel. This serves not only to automatically maintain an am le supply of material in the rece tacle, but a so serves to provide a supply 0 material sufficient to tide. over any sli ht stoppage of the flow of material from the Tiins. The said cylinders and platforms are preferably inclosed in the casing 23. Between the fixed casing 23 and the movable rece tacles are provided the cooperating channei 24 and projection 24* and the cooperating channel 25 and projection 25*. These channels are adapted to hold dust, sand, or other. material to form a substantially air-tight and dustproof movable packing or seal between the said movable parts and the stationary casing23.

The deflectors 13, 14, and 15 are supported by and adapted to rotate upon the post 16,

/ which is secured. to the stationary casing 6 5; or framework connected therewith. The adjustment of these deflectors allbeing similar the description of the means of adjustment of one will be sufficient for all.

Referring to Fig. 3, the deflector 15 is provided with the extension 26, which is adapted to project into the opening or aperture 29 of sleeve member 30. Member 30 1s ada ted to reciprocate through an aperture in ox 31, secured to casing 23. .Member 30 is also provided with a slot' 32, through which projects the stationary bar 33, which is also secured to the box 31. The adjusting screw or bolt 34 projects through the end of member 30 and has a threaded cooperation with bar 33.

This adjusting-screw 34 is provided with a collar 35, pinned thereto'within the slot 32,so

that by turning the screw in either direction vided with the plate or head 38, having peripheral graduations therein adapted to be read with respect to a fixed point marked on member 30 to m'dicate the fraction of rotation of said adj usting-screw 34, so that an extremely minute and accurate scale of the varying positions of member 30, and consequently of deflector 15, is secured. The box 31, which is secured to casing 23, inc-loses the adjusting mechanism above described. A door 39 may be provided in said box for obtaining access to the interior thereof.

In a feeding device, the combination'of a plurality of rotatable receptacles for ma terial, each receptacle comprising a cylinder and a table spaced beneath its lower edge, said cylinders being arranged concentrically, said tables being of unifornrdiameter and each table having a diameter exceeding that of its respective cylinder sufficient to sup-' ort the material at natural slope, and means for deflecting {material from beneath the lower extension of each cylinder.
